Abstract
The invention discloses an efficient drying agent and a preparing method thereof.The drying agent is mainly prepared from attapulgite, calcium chloride and macroporous silica gel.According to the efficient drying agent, attapulgite, calcium chloride and macroporous silica gel are doped according to a certain proportion and act in combination.The efficient drying agent is wide in applicable humidity range, low in price and capable of effectively inhibiting guttation, and the key technology for development of the drying agent industry is broken through.
Description
Technical field
The present invention relates to desiccant field, be specifically related to a kind of highly effective drying agent and preparation method thereof.
Background technology
Desiccant is a kind of deicer absorbing moisture from environment, is widely used in the protection against the tide of the products such as food, precise electronic, container and auto parts machinery.In recent years, enhancing along with people's environmental consciousness, increasingly favored with the desiccant that the silicate clay mineral such as montmorillonite, meerschaum and Paligorskite produce for base material, but the not high enough industry development bottleneck being always up restricting its market expansion of such desiccant hydroscopicity.Can significantly improving desiccant absorbent capacity and moisture absorption rate by adding high-hygroscopicity inorganic salt calcium chloride, but simultaneously because of the easy deliquescence liquefaction of calcium chloride, cause desiccant generation solution excessive (being commonly called as desiccant guttation), etch dries object.Along with the increase of ambient humidity, the performance of guttation problem is more serious, and is difficult to overcome, and seriously limits the expansion of its range of application.
Summary of the invention
Present invention aim at, it is provided that a kind of efficient, the simple desiccant of preparation method, the technical solution adopted in the present invention is:
A kind of highly effective drying agent, it is characterised in that be prepared from according to certain weight ratio by following components:
Attapulgite clay 50-70 part
Calcium chloride 25-35 part
Macro porous silica gel 5-15 part.
Further, the method preparing highly effective drying agent, it is made up of following steps:
A: weigh 50mL sodium chloride solution, be placed in reactor；
B: being sequentially added into a certain amount of attapulgite clay, macro porous silica gel mix homogeneously, standing is dried；
C: after drying, puts into reactor in Muffle furnace, in 300-350 DEG C, sinters 1-2h.
Further, the sodium chloride solution in described preparation process A is saturated sodium chloride solution.
The present invention provides the benefit that relative to prior art: the highly effective drying agent of the present invention, by filling a certain proportion of attapulgite clay, and calcium chloride, macro porous silica gel, three's compound action.Prepare that a kind of to be suitable for humidity range wide, cheap, and can effectively suppress the highly effective drying agent of guttation, breach the key technology of desiccant industry development.
Detailed description of the invention
Below with reference to embodiment, the design of the present invention and the technique effect of generation are clearly and completely described, to be completely understood by the purpose of the present invention, feature and effect.Obviously; described embodiment is a part of embodiment of the present invention, rather than whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art obtains under the premise not paying creative work, belong to the scope of protection of the invention.
Embodiment 1: a kind of highly effective drying agent, is prepared from according to certain weight ratio by following components:
Attapulgite clay 60 parts
30 parts of calcium chloride
Macro porous silica gel 10 parts.
The method preparing highly effective drying agent, step is as follows:
A: weigh the saturated sodium chloride solution of 50mL, be placed in reactor；
B: being sequentially added into a certain amount of attapulgite clay, macro porous silica gel mix homogeneously, standing is dried；
C: after drying, puts into reactor in Muffle furnace, in 300-350 DEG C, sinters 1-2h.
Embodiment 2: a kind of highly effective drying agent, is prepared from according to certain weight ratio by following components:
Attapulgite clay 65 parts
28 parts of calcium chloride
Macro porous silica gel 7 parts.
The method preparing highly effective drying agent, step is as follows:
A: weigh the saturated sodium chloride solution of 50mL, be placed in reactor；
B: being sequentially added into a certain amount of attapulgite clay, macro porous silica gel mix homogeneously, standing is dried；
C: after drying, puts into reactor in Muffle furnace, in 300-350 DEG C, sinters 1-2h.
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the premise without prejudice to spirit of the present invention, and these equivalent modification or replacement are all contained in the application claim limited range.
